Adding param to screens fragments 🍖

[sree-cfa]

Description of change ✍️

Adding iconFragment to screens since there might be multiple icons files in other SNE apps

Priority 🥇

Medium - we can override these locally, but they'd be nice to have in the FFL

Effect on other applications using FFB 🌊

No breaking changes - this is adding a new param to a fragment, if it's null, it will not show up

✅ Checklist before requesting a review

*Didn't update docs/tests/readme since iconName doesn't explicitly have these either

• Does the new code follow our preferred coding style?
• Does the code include javadocs, where necessary?
• Have tests for this feature been added / updated?
• Has the readme been updated?
